AI agents call get_framework_docs to retrieve information from Main without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_framework_docs only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Retrieves authoritative documentation directly from the framework's official repository. When to Use Called during i18n_checklist Steps 1-13. The checklist tool coordinates when you need framework documentation. Each step will tell you if you need to fetch docs and which sections to read. If you're implementing i18n: Let the checklist guide you. Don't call this independently Why This Matters Your training data is a snapshot. Framework APIs evolve. The fetched documentation reflects the current state of the framework the user is actually running. Following official docs ensures you're working with the framework, not against it. How to Use Two-Phase Workflow: 1. Discovery - Call with action="index" to see available sections 2. Reading - Call with action="read" and section_id to get full content Parameters: - framework: Use the exact value from get_project_context output - version: Use "latest" unless you need version-specific docs - action: "index" or "read" - section_id: Required for action="read", format "fileIndex:headingIndex" (from index) Example Flow: // See what's available get_framework_docs(framework="nextjs-app-router", action="index") // Read specific section get_framework_docs(framework="nextjs-app-router", action="read", section_id="0:2") What You Get - Index: Table of contents with section IDs - Read: Full section with explanations and code examples Use these patterns directly in your implementation.. It is categorised as a Read tool in the Main MCP Server, which means it retrieves data without modifying state.
Register the Main MCP server in PolicyLayer and add a rule for get_framework_docs: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Main. Nothing to install.
get_framework_docs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_framework_docs rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_framework_docs. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_framework_docs is provided by the Main MCP server (https://mcp.lingo.dev/main). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
